4. Cancer: Medical cannabis can help manage the symptoms of cancer, such as pain, nausea, and loss of appetite. It can also help with side effects of chemotherapy, such as vomiting and fatigue.

5. Multiple Sclerosis: Medical cannabis has been shown to help manage symptoms of multiple sclerosis, such as spasticity, pain, and bladder control.

6. Glaucoma: Medical cannabis can help lower intraocular pressure, which can help manage symptoms of glaucoma.
